Rock oil, mineral oil, or natural oil, a dark brown or greenish inflammable liquid, which, at certain points, exists in the upper strata of the earth, from whence it is pumped, or forced by pressure of the gas attending it. It consists of a complex mixture of various hydrocarbons, largely of the methane series, but may vary much in appearance, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc.
A century ago, petroleum - what we call oil - was just an obscure commodity; today it is almost as vital to human existence as water. James Buchan
To cause the face to appear in a mass of flame make use of the following: mix together thoroughly petroleum, lard, mutton tallow and quick lime. Distill this over a charcoal fire, and the liquid which results can be burned on the face without harm. Harry Houdini
I am convinced that Nigeria would have been a more highly developed country without the oil. I wished we'd never smelled the fumes of petroleum. Wole Soyinka
You hear entertainers all the time, saying, 'If I couldn't get paid for this, I'd do it for free.' When's the last time you ever heard a business person say, 'If I couldn't get paid for being chairman of British Petroleum, I'd do it for free'? Dick Gregory
There are signs that the age of petroleum has passed its zenith. Adjusted for inflation, a barrel of crude oil now sells for three times its long-run average. The large western oil companies, which cartellised the industry for much of the 20th century, are now selling more oil than they find, and are thus in the throes of liquidation. James Buchan
